Description

Bidirectional intubation tracheotomy expansion device with intubation channel

Technical Field

The invention relates to the field of medical instruments, in particular to a bidirectional intubation tracheotomy dilation device with an intubation channel.

Background

Tracheotomy is a first aid procedure, originally used only to relieve dyspnea caused by laryngeal obstruction. With the deep understanding of the pathophysiological functions of the respiratory tract, tracheotomy has become an important adjuvant therapy for some diseases. For example, in a patient who is unconscious for a long time due to various reasons, the secretion of the lower respiratory tract accumulates to influence the ventilation function of the lung, after the trachea is cut, the secretion of the lower respiratory tract can be sucked out from the cut opening of the trachea, and medicines and antibiotics for thinning and sticking the secretion can be dripped into the trachea to prevent or treat the complication of the lung. After the trachea is cut, air directly enters from the cut, so that the resistance and dead space of the respiratory tract are reduced, and under the condition of the same respiratory tidal volume, the effective gas exchange volume can be increased, the oxygen consumption can be reduced, and the respiratory function is improved. In addition, when respiratory muscle paralysis or sudden cessation of breathing is caused by other reasons, tracheotomy, positive pressure artificial respiration, or the like is performed. Therefore, doctors in various clinical departments should be familiar with the indications of tracheotomy so as to apply the tracheotomy in time and correctly treat the tracheotomy and save the life of patients.

The current commonly used methods comprise general tracheotomy, emergency tracheotomy, cricothyroid membrane dissection, permanent tracheotomy, percutaneous tracheotomy and quick tracheotomy, one of the same operations is that the trachea needs to be dissected, the interconnular fascia needs to be dilated to be enough to be placed in a tracheotomy sleeve, then a spiral dilator is placed for rotary dilation, and after the dilation is completed, the dilator is withdrawn, the incision is dilated through a dilation forceps, and then subsequent intubation is carried out. Tracheotomy is to two kinds of situations when neck trachea cannula, one is that the patient meets the proruption disease and leads to upper segment trachea to be blocked by secretion such as sputum and lead to unable normal breathing, need cut open the trachea and establish respiratory channel and guarantee patient life safety then inhale rescue processing such as phlegm. The other is that the trachea of the patient is diseased to cause tracheal stenosis, so that the patient has difficulty in breathing, and after a breathing channel is established at the neck after the trachea is cut open, the diseased narrow tracheal section is expanded and supported by a particle support to be treated. Although the above device and method can complete the operation of the endotracheal intubation on the patient, they have the following drawbacks:

1. when the narrow trachea of particle support treatment in-process pathological change appears improving in traditional tracheotomy, be in under the sacculus shutoff state at trachea cannula, the patient can't breathe through the nasal cavity, only can try whether the trachea pathological change section can ventilate after trachea cannula withdraws from. If the patient still has dyspnea when breathing through the nasal cavity, a tracheotomy tube is inserted to establish a breathing passage. The operation is very complicated, and the repeated plugging and unplugging of the oxygen therapy tube and the establishment of the channel are very decocted for patients. A conventional medial tracheotomy lacks a buffer transition phase that can be detected and tried on the patient's nasal breathing.

2. The traditional tracheotomy can only provide the patient to breathe by connecting the oxygen catheter through the intubation, and the upper section of the tracheotomy is always in the balloon blockage to the nasal cavity, so that the patient cannot breathe through the nasal cavity. The trachea obstruction is reduced after treatments such as sputum suction, when the balloon plugging of the trachea cannula is not withdrawn, the patient can not breathe through the nasal cavity all the time, the oxygen catheter needs to be communicated with the trachea cannula all the time, the oxygen catheter can not be removed for the patient, and the self-movement is very inconvenient in the mouth-nose spontaneous respiration recovery period.

3. Traditional tracheotomy lets in the sacculus pipe after the tracheotomy and carries out the shutoff to the hypomere trachea, need insert the sacculus pipe in addition through patient's oral area and carry out the shutoff to incision upper segment trachea and form airtight effect, complex operation, and need be fixed with the fixer at patient's oral area and be used for fixing the oral area and insert the pipe, the operation is very loaded down with trivial details. And the sacculus pipe exists all the time in the trachea cannula's in-process for patient's oral area is in the open state all the time and is inserted the sacculus pipe, and the throat inserts the physiology vomiting reaction of foreign matter and is very painful to the patient.

4. But the inside passageway that does not have air supply pipe intubate of traditional helical dilator, need carry out the centre gripping to the incision in addition through a plurality of expansion pincers after the helical dilation is withdrawn from and pull outward the expansion state of guaranteeing the incision, the operation is very loaded down with trivial details, and the expansion pincers very easily take place to slide at the neck when pulling outward, lead to the incision expansion to keep unstable, is unfavorable for the doctor to carry out trachea cannula. And this operation needs a plurality of doctors cooperation operation, occupies doctor's manpower and inefficiency.

5. In the traditional trachea cannula operation, the tracheostomy cannula additionally needs a doctor to manually support and fix in the process of being inserted into the trachea in the neck from the incision, so that the tracheostomy cannula also occupies the manpower of the doctor, and the treatment efficiency is reduced.
